SEAT-FRAME FOR CAR-SEATS.

Specification of Letters Patent.

Patented May 23, 1916.

To all whom it may concern:

Be it known that I, JOHN EDWIN KIL- BURN, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Seat-Frames for Gar-Seats, of which the following is a specification.

This invention relates to car-seats, and particularly to the construction of a seatframe such as is used at one or both ends of a car-seat.

The invention is directed to the provision of an improved form of seat-frame, so constructed that it may be manufactured at low cost, that it possesses ample strength, and that it is of lighter weight than the seatframes of the forms heretofore commonly employed.

A seat-frame constructed in accordance -with the invention-comprises a central portion, two arms extending upwardly therefrom and adapted to receive and support the seat structure, and two arms extending downwardly from the central portion and adapted to rest upon the floor, the seatframe being formed from two members which are secured together intermediate their ends and each of which is bent intermediate its ends so as to form two of the said arms. The two members employed in the construction of the seat-frame may be so formed that one of them constitutes part of the central portion of the frame and the two upwardly extending arms, while the other constitutes part of the central portion of the frame and the two downwardly extending arms. I prefer, however, to have the two members constituting the seat-frame so formed that each constitutes one of the upwardly extending arms and one of the downwardly extending arms. In either case, the ends of the arms are flattened out, so as to form pads, the pads at the ends of the upwardly extending arms being adapted to receive the seat structure and the pads at the ends of the downwardly extending arms being adapted to bear on the floor, so that a better seating of the seat structure on the seat-frame and the seat-frame on the floor is secured. In forming the members from which the seat-frame is made, I preferably ployed, one at each end of the seat.

employ sheet-metal. When this construction is employed, a sheet-metal strip is folded upon itself so as to bring the lateral edges of the strip together toward the ends of the strip forming the member, but these lateral edges are kept spaced apart at the central portion of the member Where the latter is to be joined to the coacting member of the seat-frame, as in this way a stronger joint between the two members may be eflected and the seat-frame is made of more attractlve appearance. In securing the two mem bers for a seat-frame together intermediate their ends, a process of welding is preferably employed, but if desired the members may be secured together in any other suitable manner, such, for instance, as by riveting them together.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is an elevation of a seat-frame, Fig. 2 is a similar view of one of the members of the frame; Fig. 3 isa cross-section through one of the arms of the seat-frame;

. Fig. 4 is a top View of the seat-frame; Fig.

5 is a central horizontal section of the seatframe.

Referring to the drawings, a seat-frame is shown such as may be used for supporting one end of a car-seat. Such a frame may be employed at the aisle end of a car-seat, while the opposite end is supported upon the wall of the car, or two such frames may be em- The seat-frame comprises a central portion 12, arms 13 and let extending upwardly therefrom and adapted to support the seat structure, and arms 15 and 16 extending downwardly from the central portion 12 and adapted to bear upon the floor. The seat structure may be of any suitable type.

In Figs. 1 and 4:, I have shown rails 17 of T section, which extend lengthwise of the seat and each of which is supported at one end upon the upper end of one of the arms 13 and 1 1; the rails 17 support the rockers for the seat-cushion and other portions of the seat structure.

The seat-frame shown in Fig. 1 is formed from two members which are secured together intermediate their ends and each of which constitutes two of the arms above referred to, as well as a part of the central portion 12 of the seat-frame. In the preferred form, each member constitutes one of the upwardly extending arms and one of the downwardly extending arms. One of these members is shown in Fig. 2. This member is formed from a strip of sheet-metal, which is folded upon itself, its lateral edges being brought together toward the ends of the member but not at the central portion of the member. Preferably the strip is bent so as to give the arms thereof the cross-sectional shape illustrated in Fig. 3, wherein it will be seen that the arm is hollow and that the lateral edges of the strip are brought together side by side. These edges are welded together as shown at 19. Along that portion of the member which constitutes part of the central portion 12 of the seatframe, the edges of the sheet-metal strip are not united, as is indicated at 20. Both ends of the member are spread and flattened out so as to form pads 21 and 22, these being preferably provided with screw-holes as shown. The pads 21 receive and support the seat structure, which is secured thereto by bolts, and the pads 22 bear upon the fioor and may be secured thereto by suitable screws. Two members, such as that illustrated in Fig. 2, are united to form the seat frame by bringing the edges 20 of their central portions together and then welding abutting edges 20, is indlcated in Fig. 1 by the two members together along these abutting edges. When so welded, the two members are secured together so rigidly that the seat-frame possesses great strength. The

seat-frame so constructed is of simple design and pleasing appearance, and though it possesses ample strength, it is of relatively light weight. The line on which the two members are welded together along their the dotted line a. 1

In accordance with the constructions which I have illustrated herein and described above, a seat-frame is produced which is superior to those heretofore commonly used, in that it is of lighter weight and though lighter in weight is of ample strength. Furthermore, seat-ends of this construction may be manufactured at comparatively low cost.

Having now described my invention, what I claim as new therein and desire to secure by Letters Patent is as follows V 1. A seat-frame for a car-seat, comprising a central portion, two arms extending upwardly therefrom and two legs extending downwardly from the central portion, said seat-frame being formed from two metallic members which are welded together intermediate their ends and each of which is shaped to form one of said arms and one of said legs, and each of said members consisting of a sheet-metal strip bent laterally into an arched formation with the lateral edges of the strip at the inside, said edges being pressed together to lie flat and secured together toward the ends of the memher but spaced apart at the central portion of the member to form an opening and having the material at the edge of the opening welded to the material at the edge of the opening in the other member, substantially as set forth.

2. A seat-frame for supporting one end,

which receive and support the seat struc-' ture, and two legs extending downwardly from the central portion and flattened out at their ends to form pads which bear on the floor, said seat-frame being formedfrom two metallic members which are'welded to- 7 gether intermediate their endsand each of which is shaped to form one of said arms and one of said legs, and each of said members consisting of a sheet-metal strip bent laterally into an arched formation with the lateral edges of the strip at the inside, said edges being pressed and welded together'to ward the ends of the member but spaced apart at the central portion of the member to'form an opening and'having the material at the edge of the opening welded to the ma terial at the edge of the opening in the other member along the abutting edges of the two members, substantially as set forth.
